- Profit The profit P, in thousands of dollars that a manufacturer makes is a function of the number N of items produced in a year, and the formula is P=0.2N2+3.6N9. a. Express using functional notation the profit at a production level of 5 items per year, and then calculate that value. b. Determine the two break-even points for this manufacturesthat is, the two production levels at which the profit is zero. c. Determine the maximum profit if the manufacturer can produce at most 20 items in a year.arrow_forward5. United States Population Growth In 1960 the population of the United States was about 180 million. Since that time, the population has increased by approximately 1.2 each year. This is a verbal description of the function N=N(t), where N is the population, in millions, and t is the number of years since 1960. a. Express in functional notation the population of the United States in 1963. Calculate its value. b. Use the verbal description of N to make a table of values that shows U.S. population in millions from 1960 through 1965. c. Make a graph of U.S. population versus time. Be sure to label your graph appropriately. d. Verify that the formula 1801.012tmillion people, where t is the number of years since 1960, gives the same values as those you found in the table in part b. Note: Because t is the number of years since 1960, you would use t = 2 to get the population in 1962. e. Assuming that the population has been growing at the same percentage rate since 1960, what value does the formula above give for the population in 2000? Note: The actual population in 2000 was about 281 million..arrow_forwardGross Profit Margin The gross profit margin is a measurement of a companys manufacturing and distribution efficiency during the production process. If G is the gross profit and T is the total revenue, both in dollars, then the gross profit margin M=M(G,T) is given by the formula M=GT a. Use functional notation to express the gross profit margin for a company that has a gross profit of 335, 000 and a total revenue of 540, 000. b. Calculate the gross profit margin in part a. The gross profit margin is often expressed as a percent. Give your answer as both a decimal and a percent. c. If the gross profit stays the same but total revenue increases, would the gross profit margin increase or decrease?arrow_forward
- Running Ants A scientist observed that the speed S at which certain ants ran was a function of T, the ambient temperature. He discovered the formula S=0.2T-2.7, Where S is measured in centimetres per second and T is in degrees Celsius. a. Using functional notation, express the speed of the ants when the ambient temperature is 30 degrees Celsius, and calculate that speed using the formula above. b. Solve for T in the formula above to obtain a formula expressing the ambient temperature T as a function of the speed S at which the ants run. c. If the ants are running at a speed of 3 centimeters per second, what is the ambient temperature?arrow_forwardSpawner-Recruit Model In fish management it is important to know the relationship between the abundance of the spawners also called the parent stock and the abundance of the recruitsthat is, those hatchlings surviving to maturity. According to the Ricker model, the number of recruits R as a function of the number of spawners P has the form R=APeBp for some positive constants A and B. This model describes well a phenomenon observed in some fisheries: A large spawning group can actually lead to a small group of recruits. In a study of the sockeye salmon, it was determined that A=4 and B=0.7. Here we measure P and R in thousands of salmon. a. Make a graph of R versus P for the sockeye salmon. Assume there are at most 3000 spawners. b. Find the maximum number of salmon recruits possible. c. If the number of recruits R is greater than the number of spawners P, then the difference R-P of the recruits can be removed by fishing, and next season there will once again be P spawners surviving to renew the cycle. What value of P gives the maximum value of R-P, the number of fish available for removal by fishing?arrow_forwardWeekly Cost: The weekly cost of running a small firm is a function of the number of employees. Every week there is a fixed cost of 2500, and each employee costs the firm 350. For example, if there are 10 employees, then the weekly cost is 2500+35010=6000dollars. a. What is the weekly cost if there are 3 employees? b. Find a formula for the weekly cost as a function of the number of employees. You need to choose variable and function names. Be sure to state units. c. Make a graph of the weekly cost as a function of the number of employees include values of the variable up to 10 employees. d. For what number of employees will the weekly cost be 4250?arrow_forward
- Resale Value: The resale value V, in dollars, of a certain car is a function of the number of year t since the year 2012. In the year 2012, the resale ale is 18,000 and each year thereafter the resale value decreases by 1700. a. What is the resale value in the year 2013? b. Find a formula for V as a function of t. c. Make a graph of V versus t covering the first 4 years since the year 2012. d. Use functional notation to express the resale value in the year 2015, and then calculate that value.arrow_forwardGeometry You want to make an open box from a rectangular piece of material, 15 centimeters by 9 centimeters, by cutting equal squares from the corners and turning up the sides. (a) Let x represent the side length of each of the squares removed. Draw a diagram showing the squares removed from the original piece of material and the resulting dimensions of the open box. (b) Use the diagram to write the volume V of the box as a function of x. Determine the domain of the function. (c) Sketch the graph of the function and approximate the dimensions of the box that yield a maximum volume. (d) Find values of x such that V=56. Which of these values is a physical impossibility in the construction of the box? Explain.arrow_forwardJuice Sales The number J, in thousands, of cans of frozen orange juice sold weekly is a function of the price P, in dollars, of a can. In a certain grocery store, the formula is J=11-2.5P. a. Express using functional notation the number of cans sold weekly if the price of a can is 1.40, and then calculate that value. b. At what price will there be 7.25 thousand cans sold weekly? c. Solve for P in the formula above to obtain a formula expressing P as a fuction of J. d. At what price will there be 7.75 thousand cans sold weekly?arrow_forward

The total cost in dollars of joining the club and buying n books is given by C=30+17n. What is the initial fee? What is the cost of each book after you are a club member?arrow_forwardReaction Rates In a chemical reaction, the reaction rate R is a function of the concentraton of the product of the reaction. For a certain second-order reaction between two substances, we have the formula R=0.01x2x+22. Here x is measured in moles per cubic meter and R is measured in moles per cubic meter per second. a. Make a graph of R versus x. Include concentrations up to 100 moles per cubic meter. b. Use functional notation to express the reaction rate when the concentration is 15 moles per cubic meter, and then calculate hat value. c. The reaction is said to be in equilibrium when the reaction rate is 0. At what two concentratoins is the reaction in equilibrium?arrow_forwardResale Value The resale value V, in thousands of dollars, of a boat is a function of the number of years t since the start of 2011, and the formula is V=12.5-1.1t. a.
